​

Answer 1

Answer:

Hope it's helpful to you please mark as branliest and follow me

Explanation:

We know that,

Y=3K(1−2σ)

or, σ= 21

(1− 2KY ) ----------(i)

Also, Y=2η(1+σ)

or, σ= 2η

Y−1 ----------(ii)

Now, From (i) and (ii),

21

(1−3KY)= 2ηY

−1or, 1−

3KY

= ηY−2

or,

Y3

= η1 +3k

Answer 2

Explanation:

We know that,

Y=3K(1−2σ)

or, σ= 21

(1− 2KY ) ----------(i)

Also, Y=2η(1+σ)

or, σ= 2ηY −1 ----------(ii)

Now, From (i) and (ii),

21

(1− 3KY )= 2ηY −1

or, 1− 3KY

= ηY −2

or,

Y3 = η1 + 3K1
